Changelog

v1.6.2

Bug fixes and improvements

  • Allow for version ~> 1.0 of the hpax dependency.

v1.6.1

Bug fixes and improvements

  • Default to using Erlang certificate store (see public_key:cacerts_get/0 and friends) if available, instead of CAStore.
  • Don't send RST_STREAM frames in HTTP/2 if they are not needed (this is a network optimization, not visible to users of Mint).

v1.6.0

New features

  • Add :case_sensitive_headers option to Mint.HTTP1.connect/4.
  • Add :inet4 option to Mint.HTTP.connect/4.

Bug fixes and improvements

  • Require Elixir 1.11+.
  • Add match_fun clause to deal with IP addresses in TLS handshake.
  • Optimize creation of HTTP/2 requests.
  • Fix a compilation warning (unused set_flag/2 function).
  • Improve performance of downcasing headers.
  • Deprecate :read_write option in Mint.HTTP.open?/2.
  • Improve performance of checking for the CAStore library.

v1.5.2

Bug fixes and improvements

  • Fix a memory leak with Mint.HTTP1 connections which would stay open but report as closed on timeouts.

v1.5.1

Bug fixes and improvements

  • Fix a FunctionClauseError that would happen when calling Mint.HTTP2.close/1 on an HTTP/2 connection that hadn't completed the handshake yet. This bug was introduced in v1.5.0. See issue #392.

v1.5.0

Bug fixes and improvements

  • Properly close sockets on erroneous connections.
  • Fix Mint.HTTP.is_connection_message/2 to support proxy connections.
  • Add support for CAStore v1.0.0+.
  • Support all HTTP/2 settings for clients as well (see Mint.HTTP2.put_settings/2).
  • Handle the first SETTINGS frame sent by the server asynchronously in HTTP/2. This means lower latency between connecting to a server and being able to send data to it.
  • Add more logging and make logging configurable through the :log option (see Mint.HTTP.connect/4, Mint.HTTP1.connect/4, Mint.HTTP2.connect/4).

v1.4.2

Bug fixes and improvements

  • Properly handle interim responses (informational 1xx status codes) in HTTP/2. Now you might get zero or more sequences of :status and :headers responses with status 1xx before the final response (with status non-1xx).

v1.4.1

Bug fixes and improvements

  • Emit the remaining buffer as a :data response when switching protocols from HTTP/1.
  • Respect closed-for-writing when streaming data frames in HTTP/2.
  • Fix handling of HTTP/2 frames of an unknown type.

v1.4.0

Bug fixes and improvements

  • Add support for SETTINGS_ENABLE_CONNECT_PROTOCOL HTTP/2 server setting.
  • Omit the :scheme and :path pseudo headers for HTTP/2 CONNECT.
  • Fix invalid connection state when data can't be sent.
  • Skip expired certs in partial chain hook.
  • Add Mint.HTTP.get_proxy_headers/1.
  • Add Mint.HTTP.module/1.

v1.3.0

Bug fixes and improvements

  • Improve compatibility with OTP 24.
  • Support HTTP/1 pipelining when streaming requests.
  • Add Mint.HTTP.get_socket/1 for returning the connection socket.
  • Improve compatibility with TLS 1.3.

v1.2.1

Bug fixes and improvements

  • Fix a bug where we were not ignoring the return value of :ssl.close/1 and :gen_tcp.close/1.
  • Fix a bug where we were not properly handling transport errors when doing ALPN protocol negotiation.
  • Fix a bug where we were not handling connection closed errors in a few places.

v1.2.0

Bug fixes and improvements

  • Fix a few bugs with passing the Mint connection around.
  • Add IPv6 support with inet6: true in the transport options.
  • Cache the :cacertfile option for faster certificate lookup and decoding.
  • Add TLS 1.3 to default versions.

v1.1.0

Bug fixes and improvements

  • Concatenate values in one cookie header if the cookie header is provided more than once in HTTP/2.
  • Fix headers merging in Mint.UnsafeProxy.
  • Remove some Logger.debug/1 calls from the codebase.
  • Assume the HTTP/2 protocol on TCP connections if using Mint.HTTP2.
  • Fix a bug where we would send WINDOW_UPDATE frames with an increment of 0 in HTTP/2.
  • Make the empty body chunk a no-op for Mint.HTTP.stream_request_body/3 (only for HTTP/1).
  • Add the Mint.HTTP.is_connection_message/2 guard.
  • Fix wildcard certificate verification in OTP 23.

v1.0.0

Breaking changes

  • Remove the deprecated Mint.HTTP.request/4, Mint.HTTP1.request/4, and Mint.HTTP2.request/4.

v0.5.0

Bug fixes and improvements

  • Deprecate Mint.HTTP.request/4 in favor of explicitly passing the body every time in Mint.HTTP.request/5. Same for Mint.HTTP1 and Mint.HTTP2.
  • Don't include port in the authority header if it's the default port for the used protocol.
  • Add a default content-length header in HTTP/2
  • Allow passing headers to proxies with the :proxy_headers option.
  • Fix a bug with HTTP/1 chunking.

v0.4.0

Bug fixes and improvements

  • Fix a small bug with double "wrapping" of some Mint.TransportErrors.
  • Prevent unnecessary buffer allocations in the connections (less memory waste!).
  • Add support for chunked transfer-encoding in HTTP/1 requests when you don't use content-encoding/transfer-encoding yourself.
  • Add support for trailer headers in HTTP/* requests through stream_request_body/3.
  • Add a page about decompressing responses in the guides.

v0.3.0

Breaking changes

  • Remove Mint.HTTP1.get_socket/1, Mint.HTTP2.get_socket/1, and Mint.HTTP.get_socket/1.

Bug fixes and improvements

  • Downcase all headers in HTTP/2 to mimic the behavior in HTTP/1.1.

  • Add Mint.HTTP.set_mode/2, Mint.HTTP1.set_mode/2, and Mint.HTTP2.set_mode/2 to change the mode of a socket between active and passive.

  • Add a :mode option to the connect/4 functions to start the socket in active or passive mode.

  • Add Mint.HTTP.recv/3, Mint.HTTP1.recv/3, and Mint.HTTP2.recv/3 to receive data from a passive socket in a blocking way.

  • Add Mint.HTTP.controlling_process/2, Mint.HTTP1.controlling_process/2, and Mint.HTTP2.controlling_process/2 to change the controlling process of a connection.

  • Support trailer response headers in HTTP/2 connections.

v0.2.1

Bug fixes and improvements

  • Fix a bug with requests exceeding the window size in HTTP/2. We were sending the headers of a request even if the body was larger than the window size. Now, if the body is larger than the window size, we error out right away.

  • Fix a bug in the HTTP/2 handshake that would crash the connection in case the server sent unforeseen frames.

  • Improve buffering of body chunks in HTTP/1.

v0.2.0

Breaking changes

  • Add the Mint.TransportError and Mint.HTTPError exceptions. Change all the connection functions so that they return these error structs instead of generic terms.
  • Remove Mint.HTTP2.get_setting/2 in favour of Mint.HTTP2.get_server_setting/2 and Mint.HTTP2.get_client_setting/2.

Bug fixes and enhancements

  • Add support for HTTP/2 server push with the new :push_promise response.
  • Add Mint.HTTP2.cancel_request/5.
  • Add Mint.HTTP2.get_window_size/2.
  • Add open_request_count/1 function to Mint.HTTP, and Mint.HTTP1, Mint.HTTP2.
  • Add open?/2 function to Mint.HTTP, and Mint.HTTP1, Mint.HTTP2.
  • Make the Mint.HTTP2.HPACK module private.
  • Take into account the max header list size advertised by the server in HTTP/2 connections.
  • Improve error handling in a bunch of Mint.HTTP2 functions.
  • Fix flow control on WINDOW_UPDATE frames at the connection level in Mint.HTTP2.
  • Correctly return timeout errors when connecting.
  • Treat HTTP/1 header keys as case-insensitive.
  • Prohibit users from streaming on unknown requests in HTTP/2.
  • Prohibit the server from violating the client's max concurrent streams setting in HTTP/2.
  • Strip whitespace when parsing the content-length header in HTTP/1.
  • Fix path validation when building HTTP/1 requests, fixes paths with %NN escapes.
